Worksheet 4 8 Properties of Trigonometric Functions

2 = ˇ. y = sin2x Pi 2Pi-1-0.5 0.5 1 Example 2 : Sketch y = 3sin2x for 0 x 2ˇ. Here the period is still ˇ but the amplitude is now 3. y = 3sin2x Pi 2Pi-3-2-1 1 2 3 Example 3 : Sketch y = 3sin2 x+ ˇ 4 for ˇ 4 x 2ˇ. The period is ˇ, the amplitude is 3 and there is a phase shift. The graph shifts to the left by ˇ 4. y = 3sin2 x+ ˇ 4 Pi 2Pi ... ................
